I agree *sigh*. I find it unlikely that House will experience healing (even physical healing) until the end of the series. He'll probably have his pain return, which is a 50% chance. But at least he might start acting a little less out of control, like he was after Stacey left.
I've pretty much come to the conclusion that the shooter represents House's Conscience (specifically), which amused me. Turns out House's Conscience is a balding, greasy-haired, and fallen entity with a soul patch that has to shoot House to get his attention.

Also, is it just me, or is the undressing-Cameron-with-a-robot-image just the perfect representation of how House relates to her? That he can't bear to get close to her without using an impersonal medium like robotic arms (or sarcasm, in the real world)?
